Problems solved by technology

[0003] At present, IEEE's existing standard 802.1AX link aggregation can realize the protection of multiple links, but it only supports port aggregation on one node, so it can only be used for link protection, but if you want to use it on the network edge interface Protect nodes, which cannot be achieved with the current link aggregation technology

Embodiment 1

[0084] Such as figure 2 Shown is a schematic diagram of the state transition of the receiving state machine. The function of the receiving state machine includes processing the received LACP protocol message, parsing the message, recording the aggregation-related information of the opposite end, and calling the selection logic module to set the selected state of the port, and setting the relevant data of the link aggregation according to the information of the opposite end. And judge whether the data related to the aggregation of the opposite end saved by the local end is aging and deal with it accordingly, and encourage other state machines of the LACP protocol to run. It is the core of the state machine of the LACP protocol.

[0085] 1. INITIALIZE (initial) state

[0086] The parameters in this state include: Selected (selected) parameters

[0087] The INITIALIZE state initializes some parameter variables, regards the peer parameter management value as the current operati...

Embodiment 2

[0105] Such as image 3 As shown in , it is a schematic diagram of the state transition of the periodic sending state machine.

[0106] The periodic transmission state machine is used to maintain the aggregation to determine whether the local end and the peer end need to exchange LACPDUs on the link, and to determine how often the periodic transmission should occur. Periodic sending will happen if required by either end. The period at which the transmission occurs is determined by the peer; this period is related to the rate at which the peer receives information timeouts.

[0107] In the periodic transmission state machine, it is necessary to determine whether periodic transmission occurs according to relevant system parameters of the DRCP.

[0108] If DRNI is not supported (Is_DRNI=FALSE), the values ​​of LACP_Enabled and port_enabled variables are TRUE at the same time and when one of the values ​​of Partner_Oper_Port_State.LACP_Activity and Actor_Oper_Port_State.LACP_Act...

Embodiment 3

[0117] Such as Figure 4Shown is a schematic diagram of the state transition of the composite state machine. The composite state machine is used to decide whether to block the port according to the selected state of the local end and the opposite end, so as to control the opening and closing of the function of receiving and sending data on the port. In this state, the DRCP module is notified in real time according to the port state change.

[0118] 1. DETACHED state

[0119] The Selected variable becomes UNSELECTED (non-selected) or STANDBY (standby) state and causes the state machine to enter the DETACHED state. Begins the process of detaching the port from the aggregator. Once the separation process is completed, the value of Actor_Oper_Port_State.Synchronization is set to FALSE, indicating that the local end considers the port OUT_OF_SYNC, and the frame distribution function of the port is closed. The value of collection state) is set to FALSE, and the frame collection ...

Abstract

The invention provides a method for cooperation of distributed elastic network interconnection systems. The method comprises the step that after an LACP system receives systemic parameters announced by a distributed relay control protocol (DRCP) system, the systemic parameters of the DRCP system are used as system negotiation parameters of the LACP system. The invention further provides an LACP system which comprises a receiving module and a control module. The receiving module receives the systemic parameters announced by the DRCP system, and the control module regards the systemic parameters of the DRCP system as the system negotiation parameters of the LACP system. By means of the method, cooperation of the LACP system and the DRCP system is achieved.

Description

technical field [0001] The invention relates to data communication technology, in particular to a cooperation method and system in a distributed elastic network interconnection system. Background technique [0002] Ethernet link aggregation is referred to as link aggregation for short. It bundles multiple Ethernet physical links together to form a logical link, so as to achieve the purpose of increasing link bandwidth. At the same time, these bundled links can effectively improve link reliability through mutual dynamic backup. LACP (Link Aggregation Control Protocol, Link Aggregation Control Protocol) is a protocol based on IEEE (Institute of Electrical and Electronics Engineers, Institute of Electrical and Electronics Engineers, Institute of Electrical and Electronics Engineers) 802.3ad standard, which can realize link dynamic aggregation and de-aggregation. [0003] At present, IEEE's existing standard 802.1AX link aggregation can realize the protection of multiple links,...
